   P&E Mission Systems — TARGET-BASED SINGLE SECTION VIEW
   Use this as the FINAL stylesheet approach if you want:
   - ONLY the selected section visible
   - No section bleeding under any viewport size
   - Section panel centered in viewport
   - Content visible via internal panel scrollbar when needed

   Required HTML shape already exists:
   <section id="..." class="section">
     <div class="container section-shell ...">
       ...
